The options for the first one. A.4 B.-4 C.0 D. both -4 and 4 the options for the second one. A.3 B.-2 C.2 D. both 2 and -2
the options for the second third. A. x - intercepts B. Zeros of the function C. Roots of the functions D. All of above

 15) D     16) D         17) D

Step-by-step explanation:

15) option D

when y = 2, x = -4 and x = +4

16) option D

when y = 0, x = -2 and x = +2

17) option D

when y=0, the x-values are the zeros.

The points are on the x-axis so are the x-intercepts.

The x-values can be found using the Quadratic Formula, which are also called the roots.

correct answers

true

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
